Cannot find style resource for iOS 15

[John van de Waeter 7]

Hi All,

I get this message "Cannot find style resource for iOS 15" when I try to rightclick an editbox on the application's mainform and select "Edit custom style".

 

My SDK points to iPhoneOS 18.2.  No Style editor is opened.  

When I doubleclick the stylebook component on the mainform, only Default and Android Light are shown in the platform combobox.

 

Any idea where to look or how to fix this?

 

using D12.3

tia, John
